Summary: High-frequency linear transducer can improve sensitivity of transabdominal evaluation for intrauterine pregnancy.

Limitations: Transvaginal ultrasound continues to be more sensitive. It also does not provide as comprehensive evaluation of adnexa.

Practice Changing? Yes

Take Home Point: This decreases need for transvaginal ultrasound, expediting evaluation and time to disposition. However, this does not replace transvaginal evaluation I the setting of suspected ectopic.
